T0 all 'whoml it may concern Be it known that I, FERDINAND I'rrNER, asubject of the Emperor of Austria-Hungary, and a i'esident ofBrooklyin-iii the county of Kings and State of New York,

`have invented certain new and useful Improvements inGasolene-Vaporizers, of

which the following is a specification.

My invention relates t0 iiieans for sup-v is a general central sectionof apparatus einbodyiilig my invention. Fig. 2 shows in enlargedsideelevation the electric heater plug detached from the supply pipe. Fig. 3is a general side elevation of the fan or rotating element of the`\'apoiizer removed vfrom its position in the apparatus, Fig. 4 is aplanof the vaporizerwith its top plate or in closing dome removed. Fig. 5 isan enlarged central section of the vaporizer taken on a line atright-angles to the view of Fig. l..

1 is a. pipe through which the mixture or gas is supplied to themanifold of a gas engine and'2 lindicates, in slide elevation the outletend ofa carburetor of any desired vtype employed for the purpose ofproducing a mixture of air and gasolene or other hydrocarbon. 3indicates the throttle controlling lever thereof whereby the supply ofthe mixture of air andgasolenev from the carbnreter to the engineinayfbe controlled.

4 indicates a vaporizcr constructed as will be presently described andhaving an inlet 5 suitablyconstructed for' connection to the pipeleadingto the carhureter and a". outlet G for Lconnection to thc pipe 1 leadingto the engine or manifold.l

The i'aporizer is preferably constructed as a casting having an innershell .4 and outer shell 4 sepa-rated v'by an annular space throughwhich a heating medium such as the exhaust or other heating medium asfor instance the Water from the cooling jacket of the engine, may becirculated for the purpose of heating the wall of the inner shell 4',

which wall, as wil e presently described, receives on its inner surfacesthe particle-s or drops of any liquid thrown on to the saine by theaction of ay dispersing cone or by the centrifugal action of the fanmounted within said inner shell. The heatiiig'medium is introduced intothe space" or heating jacket through the inlet 7 and carried away tlierefrom by the outlet 8 or Vice versa.

Mounted within the inner shell and upon an axis .preferablycoincidingpractically with the axis of the shell is a rotatable device 9in the form of a fan adapted'lpreferably to beself-rotated by the actionof the stream of air passing from the carbureter through the vaporizerto the engine. The fan 9 is preferably constructed with its hub e 9 andvancs .cast in one piece and the varies of the fan or fan wheel are.sufficient in number or of sufficient width to practically interceptthe wlio-le stream of the mixture and catch upon their surfaces any freeparticles or drops of gasolene or hydrocarbon therein.' The ranes areinclined to the plane of the fan as shown, 'in order tov cause it to bepropelled at a high speed by the action of the stream of the mixture andto throw oti' by centrifugal force the particles or drops'of liquidlodged thereon andcaiise them toI l'come into Contactl with theinnerwall of the internal shell 4"or. with parts in direct conductingconnectioii therewith. The fan ro- Vtates freely on pivot bearings l0,10', or is otherwise suitably mounted to rotate in a supporting frame11. The said frame comprises preferably a ring-1Q having diametricalcross-bars between which the blades of the fan rotate and saidframe isitself mou1ited upon a ledge 13 within the shell 4 and is fastened downin place by an inwardly ex-V tending xflangel 14 on the bottom of thecover or dome 15,as clearly shown in Fig. A5. The under side of theframehas a conical projection 16 ext-ending axially to meet the streamof the mixture iiitroducedthrough.

Ythe Vinlet 5 so as to'throw off against the walls ofthe shell 4.particles or drops of liquid hydrocarbon encountered in the miX- ture orby reason of its heated condition to cause the same to vaporize. `Anyparticles or drops which do not encounter the conc and pass on tothe fanare received by 4the blades of the letter and thrown off by ceintrifugalaction against the heated inner wall of theshell and there vaporized.'

.top vportion or end of the vapo 'By mounting'the fan `in bearings bothof which are formedor supported on the frame 11 and properly supportingthe same in the rizing chamber with the conical projection extendingaxiallytoward the inlet 5, with which the pipe leading from thecarbureter is connected, it will be' seen that no obstacles are inter dto the free ilow of the mixture and t at the stream is received in auniform manner by the cone and fan, thus insuring a completevaporization of the particles in the mixture and avoiding any tendencyof the stream to become localized on any part of A means not only islthe supply of mixture vfrom the carbureter to the vaporizer cut off atwill but likewise and at the saine time the supply of they vaportothe'engine is cut off, so that any residual gas or vaponain thevaporizer cannot pass tov the engine when the throttle controlling thesupply from the carbui'etei to the vaporizer isopci'ated.

The pipe or passage 1 between the vapori- Azer and the engine isconstructed for the rc# ce'ption of an elect-rie heater plug 20 whichmay hcfscrewed into the .opening properly formed in the side ofthe pipel and is pro- .,vided at its inner end with heating electric coil zh/asshown more clearly in Fig. 2, which heating coil takcs'theplace in theplug ofthe ordinary spark points of a spark plug l'and when lheated hyan electric current under control of the driver by means ofa suitableswitch, will heat the combustible gas or vapor circulating through thcpipe lion its way to the manifold and engine. The heater plug 20, may heconstructed on the plan of the usual spark plug modilied preferablyhowever by extending the centralconducting rod 22 (if the llSllll Splll(plug sufficiently to allow the desired length of heating coil 2l to bewound thereon. The mica or other insulation 23 is extended over theprojecting end of the pin 22 to provide insulation of the turns of theheating coil 2l from one another and from the pin, and one end of saidcoil is attached directly to the end of the rod 22 and the other end ofsaid coil to the pin 24 forming the other terminal or electrode of theplug,

The carbui'ciei operates in the usual inan- 'ner to produce as completeand perfect a mixture of the gasolene and air as is praein the` readystarting of the engine.

lfor this purpow, for altho' the vaporizer has.4 not become thoroughlyheated, the driver turns current into the elecrtic heating plug, thusheating the mixture on its way to the manifold and aiding s soon as thesaine'is fully in operationl'the electrielieater may be 'electricallydisconnected. `In the normal operation or after the engine is fullyrunning, any free pai'- ticles or drops.v of gasoleiie or otherhydrocarbon passing lfrom the carhur'eter and'eiiisting in thecentralportion of the stream of the mixture will be caught on the cone 16'andwill eventually be vaporized as soon a8 the'same becomes heated upthrough its 'metallic' connection with the heated walls of theinner-'shell .4'. The outer .portions of the stream or any portionswhosemoist particles may not be caupht by the cone, will encounter thevaries 0f t ie fan 9, which as Soon as suction is fully established,will re` volve by the action offthe stream of the mixture and at high.speed when the same is mounted on bearings suitably constructed to havelittle' friction. 'I'hese particles received on the vaues of the fanhowever, will be immediately dislodged therefrom by centrifugal actionand will he thrown against the hot surfaces on the inner wall cftlievaporizewhieh is new jacketed by Ia layer of het products ofcombustion received froml the engineer byltlie heated water. taken fromthe cooling jaclret'thcreof, as may be desired. -The consequence is thatall of the gasolene or other hydrocarbon introduced in the carbureterand enter. ing into the mixture, will, if not vapori/,ed` in theearbureter itself, be fully and coinpletely vapoiizcd, thus affording aperfectly dry gas for `supply to the engine through the pipe 1 leadingto the manifold. Owing to this complete vaporization, the engine willoperate at, a much'higher efficiency than is possible when the mixtureis supplied dircct'from the earbureter' and withl consequently lagreater.` or less amount of free moisture ofgasolenc in the gas when .itreaches the inanifriiu.

' In the ordinary operation of an automobile engine itis frequentlynecessary to slow down the engine quickly and for a short period oftime, as for instance-,in driving the car through heavy traffic. Theoperation of the carluireter throttle alone is not effective thethrottle may he quickly closed, the engine will not slow downiiniuediately. To aid in slowing down I provide the additional throttle17 in the .passage leading from the vaporizer to the engine und connectSaid thi'dttles S0 that they are opcrpted praetically'as one. Thisadditional throttle operated in connection with the usual cdi-bureterthrottle per mite the Aengine to be slowed down almost in- @n Startingthe engine and when i staiitly, as by its .means the supply-o luistiblegas from the vaporirier to the engine is ell'cctually cut olif. Duringmomentary slowingdowns of the engine by the. opera.- tion of thecon'ibined throttle, the fan, being made rather` heavy and being mountedto re- `volvo freely, will continue to revolve at high speed and whenthe power is turned on suddenly, will be in condition to receiic anyfree particles of moisture and canse Yvaporization ofthe same .in amanner already de scribed. lit ivill therefore be eeen that a t alltimes the combustible portion of the gas or mixture will be supplied tothe engine in a thoroughly vaporized condition and therei fore in bestcondition for ellicient operation.

By constructingr the pipe l le.a rlin,,` to the manifold inproper'inanner to receive the electric heater and by using said he; Linthc manner described, l attain by the nire of one heater practicallyYthe saine results that could be obtained by the use oi' a heater plugfor each cylinder ot' the engine.

AS will be seen. my invention requires no special construction ofcarbureter sheli but may be used indi flercntly with carbir reters ofany construction, it being neceasary merely to cut the connection fromsaid carbureter to thc engine and interpose the vaporizer between theoutlet pipe from the carburcter and the continuation of the pipeleading-to the engine.
